No question that if we have an injury to Triche, MCW or Cooney we would be in trouble, but you can't have an A+ option for every contingency. If that were to occur the two uninjured guards would be force fed more traditional JB-starter minutes and Mookie would have to fill in at the off guard. If it were MCW or Triche that were injured we would have an exceptionally difficult time against good pressing teams and defenses that like to get in your shorts.
If Mookie isn't here next year, than the risk becomes greater, but I still not sure you bring someone else in...who, exactly would you bring in? Maybe go out and get a David Patrick, Sam Spann quality guard....I might prefer to take my chances with the more talented forward trying to fill in and let the chips fall where they may.
